Starting with a mass produced naturally aspirated diesel engine, a turbocharged version has been developed for passenger cars. Modifications to the naturally aspirated engine include: (1) Optimization of performances to match the vehicle needs more specifically, special care has been brought to increase low rpm torque. (2) Improvement of mechanical and thermal characteristics of the engine, to withstand turbocharging. The main problems of engine to vehicle adaptation, and their solutions, are described. The general behavior of the vehicle from the viewpoints of performance, fuel economy, exhaust gases pollution and noise emission, is also reviewed. It is concluded that the turbocharged diesel is of real interest. Concerning comfort, performances, fuel economy, a vehicle equipped with this kind of engine can be advantageously compared to the one fitted with a much larger capacity naturally aspirated engine.
